The banking network in Greece is quite extensive and well organised.
There are 26 private or state-owned Greek banks with many branches,
and 24 foreign banks with headquarters in Athens and possibly
a few branches as well.
Most banks have installed automatic teller machines (ATM’s)
in their branches to offer 24 hour service and they accept all
cards. Some of these banks have also installed Automatic Exchange
machines (AEM’s).

Islands in the Argosaronic Gulf:
Small gems scattered over the sea
Aegina, Agkistri, Spetses, Hydra, Poros, Salamina and
the peninsula of Methana form the island complex of
the Argosaronic Gulf in southern Greece. Sprinkled over
the Argosaronic Gulf and steeped in ancient mythology,
these islands are small havens in close proximity to
Athens. Daily ferry connection from the port of Piraeus
makes them a lovely, easily accessible all-year-round
destination for the Athenians. Visitors here will enjoy
natural beauty, historical treasures, unique architecture,
and glamorous, yet romantic atmosphere.
